'iUNlitE SATE IEBIEDERIGH WM. BECKER, OF NEW .EL'JIHIENS, ILLINOIS FAN ATTACHMENT FOR ROCKING-CHAIRS AND GZZMRDLES.

Specification of Letters IPatent.

indented Feb. 14:, 1911 Be it known that I, Fiunonmcn WV. Bncnnn, a citizen of the Unlted States, residing at cw Athens, in the county of St. Clair and titate of ilhnols, have lnvented new and t'ul Improvements in Fan Attachments for ltocl-ringChairs and the Like, of which the tollowing is a specification.

This invention relates to improvements in fan attachments for rocking chairs, cradles, and the like. i

Une ohject of"thefinvcntionc is the provision of a device actuated by the rocking inoi ien'ient ot the chair or cradle to which it applied to direct a current of air onto the head of the occupant of the chair or cradle.

Another object is the provision of a device which may be readily applied to most forms of rim-hing chairs or cradles now in use with out necessitating any expensive alterations in the structure of the chair or cradle.

\Vith the above and other objects in view, which will more fully hereinafter appear, the present invention consists in -certain novel details of construction and arrange inent of parts, hereinafter fully described,

illustrated in the accompanying drawings,

antl'intu'e particularly'pointed out in the appended claiinsit being understood that various, changes in the form, proportion, sine,- and minor details of the device may be made, within. the scope of the appended ciainis, without departing from the spirit or sacrificing any of the advantages of tlu. in vention.

In the accompanying t lrawings, forming partot the specification;--Figurc l. a side elcvatioi'i of the device showing its applicm tion to a rocking chair. Fig. 2 is a sectional end view on the line 2-2 of Fig. 1. Fig. 3 is a detail side elevation withthe upper end portion of the tan shaft and spring rcnioved. iliig. l.- is a detail side elevation of the guide for the fan shaft. Fig. 5 is a plan view oi the same.

Similar numerals of reference are enip'loycd to designate corresponding parts thrmighout.

.hc legs of the rocking chair are desi nated by the numerals 5 and (l, the rockers one ot which i shown connecting two ol the said legs is designated by the numeral "i, and the Heat supported by said legs being designated by the numeral 8. Since those parts are all ot' wcllltnown construction a detail dei-wription or given.

The dev' .c forming part of the subject matter ol the )Z"-= "ii1 invention is shown to include a lH'tH t of substantially right anguia contour, the opposite sides of WhlCh are gnated by the iuirncrals t) and 10. Those sides; are accoun in length the longer side 5) being slightly curved to conform to the curvature el' the rocker 7. The bracket is arranged on the inner surface Of the rocker T and at a point sut'istantially intermediate the front end and the middle of the rocker, the side 5) extending parallel with the rocltcr and having openings 11 for the reccptiini cl screws or the like'which are screwed into the inner sur'lface of the rocker 7. is l en the luau-tact is positioned on the l'otfliel in the manner just described the side 10 wil extend upwariflly from the upper side of the rocker, and formed on the outer surface oi? the side this :1 lug 12, which extends over the upper side of the rocker 7, its outer end lviog slightly beyond the outer face of the fl rower 'l. l UllIlCd 0n the upper EL and adjacent to the tree end thercot is a medially disposed socket l 1 2V rcieramre now to lfig. 1. it will be seen that rxtcnding beyond one side of the seat 8 and in aliuoiaent with the bracket is a rod it. The Utllt't' end at this red is provided with an opening lit to alinc with the socket lit. The rod is adjust-ably secured to the seat in tho t'ollowing nianuer:--

11y intercom now Hi: Fig. -t it will be seen that an oblong plate to is provided with a plurality ol' :qpt ninffr; l? for the reception of srrcws by means at which the plate is secured to the lower tare ot the seat 8. Depending 'roin thiplate are a pair of spaced bosses to having aimingtransverse openings for the tttCt'tj niiutl oi tilt inner end portion of the rod l t. 'lhrcadcd into the lower ends ot the posts i are set screws 19, the inner ends of which win n binding on the rod 14 prevent move, move): cot thereof. Passing tl'ujouph "hug; 5.55 at the outer end of the rod l-l shaft 10. The lower end portion nE l '1'. is reduced as shown at it and i5. .7 rived by the socket 133. The sha. hollow and receives a.

the some need not be side oi: the lag in. o"

sha ti. iii. the L-ltlli aha tt 3?; being adjustably portion'of the shaft 20. With this construction it will be seen that the fan shaft is extensible, and may be adjusted to various distances from the seat 8. The outer or upper 5 end of the shaft 22 is provided with a trans verse opening which receives the shanks 2 1 and 25 of a pair of fan blades 26 and 27, the said shanks extending in opposite directions and being secured against displacement by means of set screws 28, extending through the upper end portion of the shaft 22.

By reference now to the drawings it will be seen that keyed or'otherwise secured to the lower end portion of the shaft 20 is abeveled pinion 29 and pivoted adjacent to the upper end portion of the side 10 of the bracket is a toothed segment 30, the teeth of which mesh with the pinion-29. The segment 30 is provided with akradial shank 31,

the function of which will presently appear.

An oscillating arm is designated by the numeral 32, the said. arm being somewhat greater in length than the length of .the longer side 9 of the bracket and havingfits 25, medial portion. pivoted to the bracket, as

shown at 33, said arm being arranged over the inner face of the bracket its pivotal point being at the point of juncture of the sides 9 and 10, or approximately so. Se

cured to one end of the oscillating arm is an angular-shaped hanger 33, the said hanger extending downwardly from the arm and i thence toward the opposite end thereof and supporting a roller 34. The opposite end of the oscillating arm 32 is provided with an eye 35, and connecting the said eye with the seat 8 of the chair is a helical retractile spring 36, the function of which is to yieldingly hold the roller 34 in engagement with the floor or other supportingsurface for the rocken Extending upwardly from the arm 32 and at a point adjacent the hanger 33 is an upright 37, the said upright being considerably less in length than the length of the arm 32 and connection between the upper end of the upright 37 and the radial arm 31 of the toothed segment 30 is established by means of a pitman 38, the opposite ends of which are pivoted to the upright and arm 31.

With this construction it will be manifest when the chair is rocked the arm 32 will be oscillated relatively to the, rocker 7, whereupon the pitman and toothed segment will be likewise oscillated and turning movement imparted to the sections of the fan shaft. It will be seen that during each complete oscillation of the rocker 7 turning movement in opposite directions will be imparted to the fan blades 26 and 27 so that a current of air will be directed onto the occupant of the chair or cradle to which the device is applied.

From the foregoing, it is evident that I have provided a device which is comparatively simple in structure and inexpensive in manufacture, embodying few parts-and these so arranged that the danger of'derangement will be reduced to a minimum.
